Test over a patented cloth (patent n° 2003 A000007)
Made according with the specification MIL STD 285 "Method of military standard attenuation measurements for enclosures, electromagnetic shielding, for electronic test purposes". (1956)

The cloth is supplied with documentation certifying the results of the measurements done with the relative technological procedures.

REPORT SUMMARY:
The shielding material shows a shielding effectiveness against the electric field from 10 Khz to 2 Mhz, changing from 55 to 70 dB.
The magnetic field, from 10 Mhz to 30 Mhz, attains values until 20 dB.
At the upper frequencies the damping attains the maximum value of 50,5 dB at 200 Mhz, while regarding the frequency bands of the cellular telephony, 900 – 1800 Mhz, the damping goes from 19 dB nearly to 33 dB.

Test method: X 10-702-2 1994 2° tirage (normalisation Fr.)

Stucture composition of the grid (without cotton cloth cover):
17.4% polyester, 9.2% turning copper, 7.4% carbon polyester, 46.8% viscose, 19.2 % bare copper.

Test over gas generated by combustion according with the specification:
AFNOR NF X 70-100-1 (2001), MIP 018 (2002), MIP 004 (1998), AFNOR NF X 70-100-2 (2002).
